Cost per Wp is also affected by the size of the PV system, variations in the quality and features of systems and components, services provided by the seller of implementor, and input factor cost differences among countries Source: Table 2-1. 6 Table 2-2 compares unit costs for solar home systems by component in the Dominican Republic, Indonesia, and Kenya. There are significant opportunities for reducing costs through high-volume purchases of modules and other components; assembly line solar home system manufacture/integration; better utilization of production, sales and service capacities; reduced taxes and duties on PV panels and components; and larger sales volumes which would allow dealers to reduce their margins (see Box 2-1).

After the first PV project was initiated, demand for solar home systems grew faster than the program could accommodate. This led to the creation of the Philippine/German BMZ/GTZ Special Energy Program (SEP) in 1987. The SEP's strategy is to distribute small solar home systems in clustered sites, gradually increasing the demand for electricity and the area covered until grid extension becomes economically feasible. Rural cooperatives oversee servicing and fee collection, and local NGOs have direct responsibility for collections, maintenance, and monitoring.
